Class DBBigInt

java.lang.Object
  net.pleso.framework.client.dal.db.types.DBBigInt

All Implemented Interfaces:

IDBValue, INullable

public class DBBigInt
extends java.lang.Object
implements IDBValue, INullable

Database BigInt type. Internally presented like special BigInt type. see Language Support However, there is no 64-bit integral type in JavaScript, so variables of type long are mapped onto JavaScript double-precision floating point values.

Field Summary

static BigInt

nullValue Predefined BigInt null value.

Constructor Summary

DBBigInt()
Constructs new DBBigInt with null value.

DBBigInt(BigInt initialValue)
Constructs new DBBigInt with specified initial value.

Method Summary

BigInt	getBigInt()
java.lang.String	getValue() Returns string representation of current value, held in implementation.
boolean	isNull() Checks whether value of instance equals null.
boolean	parseValue(java.lang.String value) Parses string representation of value to represented type and assigns parsed value to self.
void	setNull() Sets instance value to null.

Field Detail

nullValue

public static final BigInt nullValue

Predefined BigInt null value.

Constructor Detail

DBBigInt

public DBBigInt()

Constructs new DBBigInt with null value.

DBBigInt

public DBBigInt(BigInt initialValue)

Constructs new DBBigInt with specified initial value.

Parameters:

initialValue - a initial value for newly constructed db value

Method Detail

isNull

public boolean isNull()

Description copied from interface: INullable

Checks whether value of instance equals null.

Specified by:

isNull in interface INullable

Returns:

true if instance value is null

setNull

public void setNull()

Description copied from interface: INullable

Sets instance value to null.

Specified by:

setNull in interface INullable

getValue

public java.lang.String getValue()

Description copied from interface: IDBValue

Returns string representation of current value, held in implementation.

Specified by:

getValue in interface IDBValue

Returns:

string representation of value

parseValue

public boolean parseValue(java.lang.String value)

Description copied from interface: IDBValue

Parses string representation of value to represented type and assigns parsed value to self. If string value equals null implementation must try to set itself to null.

Specified by:

parseValue in interface IDBValue

Parameters:

value - string representation of value

Returns:

true if value parsed and assigned successfully

getBigInt

public BigInt getBigInt()

Returns:

a BigInt value of instance
